A is curve shape coefficient, is used for adjusting bent curvature of a curve, and applicant finds after carrying out lot of experiments, works as a
Span when 5～20, the Quasi-TEM mode good transition to SSPPs pattern can be realized, i.e. fill
Divide and decrease L1And L3Microwave electric field reflection when being directly connected to.In addition, this utility model is also at changeover portion
The tipper of degree of depth gradual change is distributed on transmission line；By this structure, can realize further Quasi-TEM mode to
The transition of SSPPs pattern, reduces microwave electric field reflection；Reflect by reducing electric field so that of the present utility model
Loss reduce.This utility model is by arranging a series of tipper in metal micro-strip；By this
Structure so that electromagnetic wave is bound in tipper notch when transmission, thus greatly reduces a plurality of transmission
The electromagnetic interference occurred because spacing is the least during line transmission so that capacity of resisting disturbance is greatly enhanced, also increases simultaneously
Stability during strong high density microwave integrated circuit work, moreover, because of anti-electromagnetic interference capability significantly
Strengthening, this utility model can also reduce the spacing between the metal micro-strip of microwave integrated circuit to realize the little of device
Type, thus the development of current extensive microwave integrated circuit can be better adapted to.This utility model can also lead to
Overregulate the physical dimension of tipper to regulate and control cut-off frequency and the magnetic distribution of microwave transmission line, adjust simultaneously
The constraint effect effect of whole electromagnetic wave, applicant finds after carrying out lot of experiments, when taking of width of rebate w1
Value is 1～3mm, and the value of groove depth Ch1 is 2～6mm, and the value of the tilt angle theta of tipper is 15～45 °,
When tipper period p is 2～8mm, electromagnetic field is had and well fetters effect by tipper.
In order to preferably prove the beneficial effects of the utility model, application has carried out following experiment: applicant sets
Count a tipper phasmon type microwave filter sample, the parameter of sample such as table 1.
Table 1 microwave filter sample each several part parameter
The dielectric constant of the dielectric-slab of this sample is 2.65, to the filtering curve of this sample through Finite Difference-Time Domain
